BLK_QUEUE_END_TAG(9) Block Devices BLK_QUEUE_END_TAG(9)
NAME
blk_queue_end_tag - end tag operations for a request
SYNOPSIS
void blk_queue_end_tag(struct request_queue * q, struct request * rq);
ARGUMENTS
q
the request queue for the device
rq
the request that has completed
DESCRIPTION
Typically called when end_that_request_first returns 0, meaning all transfers have been done for a request. It's important to call this
function before end_that_request_last, as that will put the request back on the free list thus corrupting the internal tag list.
NOTES
queue lock must be held.
